Top Definition
When the either one or both of the vagina lips are swollen. mostly likely caused by a yeast infection, a latex allergy, a spermicide allergy, or rough sex while not properly lubricated. Sometimes it can be painful or itch. The best way to deal with it is to always wear liners, avoid super tight clothing as they cause yeast infections, and find out if you have allergies to latex or spermicide. If you have a Vaginasaurous in your pants, it helps to place a small ice pack in your panties to help ease the swelling.
Jane was scared when after sex her vagina was swollen. She asked her best friend what to make of it and she simply said, "Don't worry. You just have a slight case of Vaginasaurous."
